Contradiction with Numbers 18:20
This verse states that the Levites shall have no inheritance in the land, whereas Joshua 21:6 talks about Levites receiving cities and lands.
Numbers 18:20: And the LORD spake unto Aaron, Thou shalt have no inheritance in their land, neither shalt thou have any part among them: I [am] thy part and thine inheritance among the children of Israel.
Contradiction with Deuteronomy 10:9
This verse emphasizes that the Levites have no portion or inheritance with the tribes, contrasting with the allocation of cities in Joshua 21:6.
Deuteronomy 10:9: Wherefore Levi hath no part nor inheritance with his brethren; the LORD [is] his inheritance, according as the LORD thy God promised him.
Contradiction with Ezekiel 44:28
In this verse, it's mentioned that the Levites' inheritance is the Lord, which could be seen as contradictory to them receiving specific lands and cities as in Joshua 21:6.
Ezekiel 44:28: And it shall be unto them for an inheritance: I [am] their inheritance: and ye shall give them no possession in Israel: I [am] their possession.
